The simulation of droplet motion by using lattice boltzmann method

SCMP (Single Component Multiphase) - LBM (Lattice Boltzmann Model) scheme was developed in order to simulate the phenomenon of droplet motion under different conditions. This study more concern on phenomenon of droplet falling from a flat ceiling and the movement of droplet on inclined surface. Vari...
